Welcome to exploring Large Language Models (LLMs) — the smart engines that understand and generate human-like text. Let’s dive into this interesting world together, keeping things simple and clear.
Understanding the Basics
What are Large Language Models?
Large Language Models are advanced computer programs. They use deep learning to process and create text that’s similar to how we humans talk and write.
How Do They Work?
At their core, LLMs have a digital brain called a neural network. This brain learns from tons of text during training, picking up patterns and language details. The result is a model that can predict and create text almost like a human.
